AEM co-developed its new wideband sensor with global automotive supplier FAE, culminating in a new design that has a faster response time and is less prone to failure in high performance vehicles. It can be used on EFI or carbureted applications, and in fuel systems using gasoline (including leaded race gas), methanol, ethanol, diesel, propane, and CNG. The X-Series Wideband AFR Gauge (PN AEM 30-0300) mounting surface measures 2 1\/16th-inch (52mm) in diameter and features a modern center display that is 87% larger than the 30-4110 AEM Wideband Gauge's center display. Its slim depth (less than one inch overall) dramatically increases its application base and potential mounting locations.The AEM Wideband X-Series AFR Gauge has a user configurable display via buttons on the gauge face that allows you to change between AFR, Lambda, or O2%, change the center display to three or four digits, perform a free-air calibration if desired, and change the CAN message ID when linking multiple X-Series Wideband Controllers. X-DIGITAL TECHNOLOGY X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controller's high-speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value. WHY RESPONSE TIME MATTERS Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases can affect deadtime, it is not the only source. Often, the sensing element’s response to the gas is the largest contributor to deadtime.When tuning an engine using wideband AFR feedback control, deadtime affects the data you are looking at because it is reported in a different operating location than when it occurred. This means whatever changes you make to the base fueling will likely be in the wrong timeframe. This can be particularly dangerous to high cylinder pressure applications, and EFI systems that use feedback control.\u003c\/div\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eX-Series Wideband UEGO AFR Controller Gauges were the fastest responding wideband air\/fuel ratio controllers in an independent test vs. 17 competitor wideband AFR controllers\u003c\/li\u003e\n\u003cli\u003ePatented X-Digital wideband technology (Patent 9,575,030)\u003c\/li\u003e\n\u003cli\u003eFactory calibrated resistor does not require free-air calibration, but can be free-air calibrated\u003c\/li\u003e\n\u003cli\u003eAuto-Sensor Detection between AEM FAE and Bosch LSU 4.9 wideband sensors\u003c\/li\u003e\n\u003cli\u003eCompatible with supply voltages up to 16V\u003c\/li\u003e\n\u003cli\u003e0-5V \u0026amp; RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders\u003c\/li\u003e\n\u003cli\u003e52mm gauge diameter and slim 0.825\" gauge depth(Gauge cup depth only .200\" deep)\u003c\/li\u003e\n\u003cli\u003eAuto-dimming feature\u003c\/li\u003e\n\u003cli\u003eUser-configurable display for changing between AFR, Lambda, and O2%, and 3- or 4-digit display\u003c\/li\u003e\n\u003cli\u003eBlack bezel and black double-sided faceplate included (silver bezel\/white faceplate option sold separately, PN 30-0300-ACC)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AEM","offers":[{"title":"Default Title","offer_id":44206404370531,"sku":"30-0300","price":222.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/3978\/0195\/files\/aem1.avif?v=1779589360"},{"product_id":"aem-x-series-obdii-wideband-afr-gauge-kit","title":"AEM X-Series OBDII Wideband AFR Gauge Kit","description":"\u003cdiv class=\"full_description\"\u003eAEM's X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge (PN 30-0334) provides tuners who are using piggyback tuning modules or open source software with the ability to view AFR through the factory CAN-bus stream that is output by the factory ECU, and deliver the most accurate, safe and powerful tune. The 30-0334 X-Series OBDII Wideband Gauge is validated to work with DiabloSport in Tune 3, Trinity 2, EFILive, HPTuners and DashDaq software.The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through connector and 4.9LSU sensor that can be free-air calibrated or used with the factory resistor calibration. Additional wiring for a 0-5v or RS232 Serial output can be added by the user for outputting to a data logger. This OBDII pass-through capability replaces the traditional AEMnet stream available in the 30-0300 X-Series Wideband AFR Gauge Controller.OBDII CAN-bus OUTPUTThe OBDII output simulates an auxiliary ECU signal when plugged into a vehicle's OBD port, which requires a unique address from the other ECUs already on a vehicle's network. AEM's default OBDII CAN address will work with most popular vehicles and adjustments should not be necessary.

A 52mm (2-1\/16\") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air\/Fuel Ratio faceplates).The UEGO sensor gives the controller its speed and accuracy. The 4.9 LSU sensor used in the 30-4110 AEM Wideband UEGO AFR Controller Gauge has a faster light-off time and draws less current than the 4.2 LSU sensor used with AEM's 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August 2014. The 4.9 LSU sensor features the same fuel compatibility as the 4.2 LSU and NEVER requires free-air calibration when used with AEM's 30-4110 Wideband UEGO AFR Gauge. The 30-4110's 4.9 LSU sensor uses a different connector than the connector used with the 4.2 LSU sensors included with the original 30-4100 gauge controller. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges.The Wideband O2 air\/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air\/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage.

The X-Series Wideband UEGO Air\/Fuel Ratio Controller replaces the popular 30-2310 Inline Controller.X-Series Inline Wideband UEGO Controller features a weather-resistant, low-profile enclosure with status LEDs. It is ideal for users who do not need a gauge display and want the fastest response time when data logging or for feedback control when tuning with an engine management system. The X-Series Inline Controller includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging and daisy chaining multiple X-Series Controllers together (up to 16 cylinders) for recording AFR in multiple cylinders.

AEM's legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air\/fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED \"needle\" that changes colors as AFR changes from rich to lean. AEM tested many sensors with the 30-4110NS, including popular inexpensive knockoff sensors, and determined that only the following sensors will deliver reliable performance: Using the above sensors ensures that the factory sensor calibration is accurate and that the controller performs optimally. The use of any non-approved sensor may affect the controller's operation, and will void the warranty of the 30-4110NS. WHAT IS A WIDEBAND UEGO AIR\/FUEL CONTROLLER? AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced \"You-Way-Go\") Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air\/Fuel Ratio (AFR) of their engine. WHY USE A WIDEBAND AIR\/FUEL CONTROLLER? Accurate AFR data is critical when tuning an engine. Running rich (very low air\/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air\/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air\/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air\/fuel controllers that can help ensure your vehicle is optimally tuned. WHAT IS FREE-AIR CALIBRATION? Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels.

It reads Diagnostic Trouble Codes (DTCs) and gives you the ability to clear codes. Wiring is as simple as connecting the gauge to your vehicle's OBDII port using the supplied connector! Because the X-Series OBDII gauge reads OBDII parameters transmitted through a vehicle's CAN datastream, it will only work on 2008-2024 model year vehicles. EASY TO USE Use the 'Page' button on the gauge face to scroll through available channels of data transmitted through the OBD port. Possible channels are listed below and may include IAT, EGT, RPM, Ethanol %, MAF, Fuel Pressure, Manifold Pressure, Boost Pressure, TPS, Vehicle Speed, Lambda and more (channel availability is ultimately dependent upon what channels are programmed to transmit by the vehicle manufacturer). READ \u0026amp; CLEAR TROUBLE CODES The 'DTC' button tells the gauge to scan for trouble codes and will report any stored DTCs, allowing you to look them up and determine the course of repair. This button also allows users to cleat DTCs once the problem is resolved.

Will work as a standalone gauge or can be integrated into your engine management to read out a wide array of data. AEM's X-Series Inline Wideband UEGO Air\/Fuel Ratio Controllers are built upon unique, patented, 100% digital technology that makes them the fastest responding wideband air\/fuel ratio controllers in independent testing*. The X-Series Wideband UEGO Air\/Fuel Ratio Controller replaces the popular 30-2310 Inline Controller. X-Series Inline Wideband UEGO Controller features a weather-resistant, low-profile enclosure with status LEDs. It is ideal for users who do not need a gauge display and want the fastest response time when data logging or for feedback control when tuning with an engine management system. The X-Series Inline Controller includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging and daisy chaining multiple X-Series Controllers together (up to 16 cylinders) for recording AFR in multiple cylinders. It supports vehicle\/system voltages up to 16V, and can be used on EFI or carbureted applications, and dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane and CNG. PATENTED X-DIGITAL TECHNOLOGY Patented X-Digital wideband technology (Patent 9,575,030) gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controller's high speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value. WHY RESPONSE TIME MATTERS Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Series digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases (transport delay) can affect deadtime, it is not the only source. Often, the sensing elements response to the gas is the largest contributor to deadtime when an engine is in high RPM under load. When tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the data you are looking at because it is reported in a different operating location than when it actually occurred. This means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location. This can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto tune. Reducing deadtime improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Series digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.\u003c\/div\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eX-Series Inline Wideband UEGO AFR Controller were fastest responding wideband air\/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers\u003c\/li\u003e\n\u003cli\u003ePatented X-Digital technology (Patent 9,575,030)\u003c\/li\u003e\n\u003cli\u003eIncludes Bosch 4.9LSU wideband UEGO sensor\u003c\/li\u003e\n\u003cli\u003eFactory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires\u003c\/li\u003e\n\u003cli\u003eCompatible with vehicle\/system voltages up to 16V\u003c\/li\u003e\n\u003cli\u003e0-5V \u0026amp; RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders\u003c\/li\u003e\n\u003cli\u003eWeather-resistant, low profile design\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AEM","offers":[{"title":"Default Title","offer_id":44206413217891,"sku":"VK080036","price":635.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/3978\/0195\/files\/aem13.avif?v=1779590654"}],"url":"https:\/\/heltonchassisandfab.com\/collections\/gauges.oembed","provider":"HELTON CHASSIS AND FAB","version":"1.0","type":"link"}
